Stretching the limits of dark matter searches with springy detectors

Title: “The Piezoaxionic Effect” Authors: Asimina Arvanitaki, Amalia Madden, Ken Van Tilburg Link: https://arxiv.org/abs/2112.11466 We can’t find the missing five-sixths of the universe called dark matter because it doesn’t collide in detectors — but what if it shakes them? Today’s paper theorizes a new kind of stretchy detector that rapidly shrinks and expands in dark matter’s presence, creating a tiny vibration that can be measured. Old hypothesis, new effect Many physicists think dark matter.
